BIOPHOTON FACTS--->Biophotons are super weak flashes of light (ultraviolet to visible wavelengths) emitted by living cells and organisms, like plants, animals, and even humans. They're not the bright glow you see in fireflies—instead, think of them as tiny, random sparks from biochemical reactions inside cells, too faint for the naked eye to detect without special equipment. Discovered in the 1920s by Russian scientist Alexander Gurwitsch (who called them "mitogenetic rays") and later studied by German physicist Fritz-Albert Popp in the 1970s, biophotons are measured in photons per second per square centimeter—often just a few dozen to thousands, compared to trillions from a light bulb.Why Do Living Things Emit Biophotons?At the cellular level, biophotons come from everyday chemical processes:Oxidative reactions: When cells use oxygen to break down food for energy (like in mitochondria), excited molecules release photons as they return to their normal state. This is similar to how glow sticks work—chemical energy turns into light.
DNA and proteins: These molecules can absorb and re-emit light during replication or signaling. Popp's research showed DNA acts like a "light antenna," coherently organizing these emissions, possibly for cell communication.
Evidence: Lab experiments using photomultiplier tubes (sensitive detectors) confirm healthy cells emit coherent, low-level light patterns. Stressed or dying cells show chaotic bursts. For example, a 2005 study in Journal of Photochemistry and Photobiology measured biophoton emissions from seed germination, linking higher coherence to faster growth.
Do They Have a Purpose?Scientists debate this, but evidence suggests biophotons might help cells "talk" to each other:Cell signaling: In plants, they could coordinate growth or stress responses. A 2014 review in Frontiers in Physiology proposed biophotons enable ultra-fast communication via quantum effects in microtubules (cell "highways").
Health indicators: Cancer cells emit more biophotons due to metabolic chaos, as shown in Popp's work and a 2011 PLoS One study on human skin cells. This could inspire non-invasive diagnostics.
Not fully proven: Mainstream biology sees them as harmless byproducts of metabolism, not deliberate signals. Critics argue detection artifacts or external light interference explain some findings, but replicated experiments (e.g., on delayed luminescence in algae) support their existence.
Fun Facts for High SchoolersHuman glow: Your body emits about 10-100 biophotons per cm² per second, peaking from the head and hands. It's why some "ultra-weak chemiluminescence" studies link it to oxidative stress.
Detection: Use a dark room, sensitive CCD cameras, or photomultipliers. DIY versions exist with phone sensors, but they're unreliable.
Applications: Potential in medicine (e.g., monitoring wound healing) or agriculture (assessing plant health). Research continues, with Popp's International Institute of Biophysics advancing coherent photon theories.
Biophotons blend biology and physics, hinting at quantum biology's role in life—check out Popp's book Biophotons or Gurwitsch's original papers for deeper dives (accessible summaries online). Experiments are ongoing, but they're a cool window into life's hidden light show!
